booker killing himself would be the best ending, ends everything 1 go.

but both booker and comstock are in different timeline, right? so when lutece got anna and open the portal, the portal is from another timeline. then lutece managed to bring booker to the timeline and rescue elizabeth.

Basically it was an infinite loop but in the end the actions done made one timeline disappear completely thus leaving us with one timeline only that didnt continue the loop.

but who created the tear to bring us to see the future Liz? Was it future Liz herself or was it the female Lutece? I cant rmb eh.

"Comstock is Booker, Booker is comstock. Due to Quantum Tech it can bent time and space where 2 same chracter can appear at the same time.

The after credit is the begining of Comstock where Booker actually accepted Beptis, and take good care of Anna or what ever and then they meet the Quantum Tech scientist and created Columbia, So dont know what happen Comstock is sterile? heard from 1 forumer and took alternative of Booker where he refuse Beptise resulting of him with Anna and got a baby child. So Comstock took this Child which is elizabeth and raise him.

And dont know why and what happened (maybe another alternative of him self where he didnt meet Anna, where he owe lots of depts then sent him(the quantum scietist) to Columbia to clear his dept. Mana tau it is to fit the purpose to keep this infinite loop going on to form the storyline and the city and Elizibeth /whole mechainics"

So this game really mindfcuk me, at first i thought it is rescuing game, where at the end Liz will be together with Booker. But ohhh my good... Liz is Booker Daughter, @_@, Comstock is actually Booker @_@, City Created is actually to protect Liz @_@ OMGGGGG...

But what a beautiful game =)

The ghost was materialized from another into this reality by Elizabeth's power ?

It sucks that firstly, you can't kill them.
Secondly, they were supposed to be blind but with super hearing senses (hence the big horns around their ears and the name, no?)..
Also in the earlier interview about them, they were supposed to be walking 'sentries' that hunt you down. But...nope. They were easy to slip by (you can RUN by in fact), only stood still while shining their spotlight all over, and not much of a fight honestly. Kinda disappointing. However that one part where you flip around and see him in your face spooked me. xD (It happened in Bioshock 1 too!)

She was created using Liz's power that was siphoned by her, hence she was Lady Comstock physically (her dead body) but mentally she was what Liz thought she really was in her mind (the ghost's behaviour)

it's was hinted early in the game that Elizabeth is Anna. At the beach, before buying the tickets for the Queen Passage, a woman soldier called Elizabeth as Annabelle, She even called Liz twice as Anna.

just random findings
